How to add 5G configurations to your Pixel 5 (solved)

[deepsync]

Hi all
Similarly to the Oneplus 8 series, Pixel 5 does not support 5G in countries that it is not sold in. For Oneplus, configurations could be changed using the Qualcomm QPST file manager.

https://mt-tech.fi/en/modify-oneplus-7-pro-5g-8-and-8-pro-nr-lte-a-band-combos/

However, using those instructions doen't work as I cant trigger engeneeringmode/factorymode.

Any idea how this could be triggered on Pixel 5 devices?

I'm also looking for advice on this, especially about adding VoLTE support aswell. Hopefully someone with more knowledge could provide some more information!

I'm even willing to contribute to a bounty

Is there anyone that understands how to get into engineering mode?

AFAIK there is no engineering mode on Pixels. Apparently there is a Qualcomm tool that allows you to modify your EFS partitions to change your bands.

There must be an engineering or factory mode - its a qualcomm chip isn't it?

I think I managed to activate engineering mode as QPST now regognizes my phone. I followed the steps by @cstark27 written here: https://forum.xda-developers.com/showpost.php?p=83499679&postcount=75

However, if I understood correctly, PDC tool is the one used to get VoLTE working on devices which are not certified between Google and a carrier by applying a vertified carrier's policy profily to your phone. Unfortunally, PDC does not regognize my phone for some reason. I really don't know what I should modify in EFS tool to enable 5G, VoLTE and more CA combos.

This has been an interesting but challenging project as I have combined steps from many tutorials designed for pixel and oneplus devices. But now I'm stuck and would love to hear comments from others who have tinkered around with these tools.

Is root a mandatory step? Wasn't for oneplus.

At least in my experience, definatelly yes. I have no idea how the diagnosing mode could be activated without it.

I don't have the Pixel 5 anymore, but looking at the carrier_policy.xml noted in the MT-Tech article (https://mt-tech.fi/en/modify-oneplus-7-pro-5g-8-and-8-pro-nr-lte-a-band-combos/), then there is a section that explicitly enables 5G for the PLMN's given. (<!-- START RULE: Add carriers require to enable 5G -->) So you should try adding your carrier to that area, copying the file back (make a backup!!) and rebooting. You can reference the PLMN name from the list at the beginning of this file...look at the MCC-MNC combos and find yours. The linked article is a little more detailed about how to do this. Proceed at your own risk. Make sure you have backed up the original files, and have the stock images to reflash if necessary.
@Lemon200 if you don't have the GD1YQ Pixel 5, this website (run by Mt-Tech admin) would appreciate the CA combos info. You can get that info using the Qualcomm Diag instructions, then upload the file to his uploader below: https://cacombos.com/contribute

I don't know about PDC. Can't get it to recognize a device.

What made you get rid of the pixel 5 @cstark27 ?

What made you get rid of the pixel 5 @cstark27 ?

Pros/cons vs the 4 XL I already have But I'm gonna do the trade-in deal with T-Mobile to get half off a 4a 5G. Will just need to get it sim unlocked so I can root it.

Thanks! I'll try enabling 5G when I have more time to mess around with QPST and upload the CA info aswell.

 

[alonsosjumper]

Could you please give an answer when you try it? I can't use in Spain the 5G network...

Good news everyone! I managed to enable 5G connectivity for my Pixel 5 in Finland. Thanks again to @cstark27 for hinting me to the right direction.

1. First you need to get your phone to show up in QPST. This is done similarly to Pixel 4 XL and you can find the the steps to do so here: https://forum.xda-developers.com/showpost.php?p=83499679&postcount=75
2. Once you have installed QPST open EFS tool. If you have followed the steps in the previous step and have the right drivers installed your phone shows up here. Now you need to navigate to the carrier policy file. More details here: https://mt-tech.fi/en/modify-oneplus-7-pro-5g-8-and-8-pro-nr-lte-a-band-combos/
3. PLEASE remember to backup the original file! Pixel 5's file is different from the OnePlus example linked above. I simply added 5G to every rat_capability field, saved the file and then replaced the original file with the modified one. As usual, you have all the responsibility of your device and its modifications.​

Now that 5G is working, all that's left is to find a way to enable VoLTE. Replacing MBN files has worked in other devices so perhaps it could be the solution here as well.

For some reason it is not working for me , i cant see my device qpst.. idk why i did it over 10 times now and still the same.

Is there anyway this is happening due to me using the method to bypass the safety net ? because for some reason my device shows as pixel 3a or something.

If you have the time can you give us the exact steps ? im pretty sure im missing something i just dont know what am i doing wrong.

Is there a way that i need specific drivers for QPST ?​

If you want to mess with QPST:
Code:
adb shell
su
resetprop ro.bootmode usbradio
resetprop ro.build.type userdebug
setprop sys.usb.config diag,diag_mdm,adb
diag_mdlog
cancel (ctrl+c) once it starts to "hang" at failed to open diag socket
change usb config (file transfer, no file transfer)
wait

It actually worked bro ! Im so happy and sad now. I tried replacing the file but 5g still not working.
you mind sharing the carrier file you edited ? if it doesnt include any private info for sure.



when i open 4634
it shows
NR Available: False
NR State: NONE
NR Frequency: UNKNOWN ?

When I try to restrict it to NR ONLY the singal dies and shows no service..


can you confirm if this is normal or it should show available for NR ?

Hi, can you please explain how can i add QPST to my phone?

Are you sure you added 5G to every field possible? There are four rat_capability fields in the file so add 5g to every one of them to be sure, although I would guess that the last one is the one which matters. After uploading the modified file to your phone a restart is required. Also I think these configs are reset when sim card is changed.

EDIT: Also NR only won't work, as current 5G NSA networks still rely on 4G in many ways.

If by this you mean how to get your phone to show up in QPST, follow the original instructions here: https://mt-tech.fi/en/modify-oneplus-7-pro-5g-8-and-8-pro-nr-lte-a-band-combos/
You need to install the diag drivers and then use the adb shell commands you mentioned in your earlier post. Please read the articles linked in my original post. The diag mode on Pixel 5 is essentially enabled with the adb shell commands in order to use qpst.
